Where do you live? If you can, I'd go to the Fraser River in BC instead, unless you wanted to keep the sturgeon (it's catch and release only in BC). I think you have a much better shot at catching a big sturgeon up there. We went last year and the river was totally blown, but our guide Merr at Harrison Hot Springs put us on a dozen or so fish, with the biggest being 8' and 5'-6' being average. The big one took 30 minutes to get in on heavy braid and tight drag.
